The following table describes the labels in this screen.
4.4 The RADIUS Screen
Click WLAN > ESSID Definition > RADIUS to open this screen. This is where you can
configure the RADIUS servers list that the NXC-8160 can use for secure authentication.
RADIUS is a common authentication protocol utilized under the 802.1x security standard
(often used in wireless networks). Although RADIUS was not initially intended to be a
wireless security authentication method, it improves the WEP encryption key standard when
used in conjunction with other security methods such as EAP-PEAP. In an enterprise
environment, several RADIUS servers may be used for backup and also for serving different
geographical locations.
Up to four different RADIUS servers can be defined for each ESSID. RADIUS redundancy is
based on the assumption that the user database is identical in all RADIUS servers and that
users are listed in all servers with the same credentials.
Switchover from one RADIUS server to another takes place after consecutive failures of the
server. The order of priority is 1 to 4.
